I'm wondering if this is true. Found this tid bit of information in the maintainence section over at woodheat.org.
You can purchase gasket cement in a small tube or tub. If you can't find gasket cement don't despair. You can use common silicone sealant in a caulking tube. Some have said that silicone hardens the gasket sooner than stove cement, but that's not a clear consensus, so don't be afraid to try it. High temperature silicone is not necessary because the temperature rating of household grade seems to work well enough.
